GAS-STOVE AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 680,017, dated August 1, 1899.

Application filed October 9, 1897. Serial No. 654,685. (No model.)

To all 1072 0772, it may concern.-

Be it known that I, HENRY M. WILLIAMS, a citizen of the United States, residing at Fort lVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Gas-Stoves and Ventilators, of which the following is a specification.

This invention relates to certain new and useful improvements in combined gas or vapor heating-stoves and ventilators, having for its object to improve the construction and efficiency of such stoves generally; and the invention consists in the novel construction, combination, and arrangement of the parts hereinafter more particularly described;

In the accompanying drawings, forming a part of this specification, and in which like letters and numerals of reference designate corresponding parts, Figure 1 is a vertical sectional view of a stove embodying the invention'. Fig. 2 is a horizontal sectional view on the line x :0 of Fig. 1. Fig. 3 is an enlarged sectional View of one of the heated air-columns. Fig. 4c is an enlarged detail sectional View of the damper controlling the flow of hot air from the generator to the discharge-flue.

Referring more particularly to the drawings, A designates the base of the stove, mounted upon suitable supports 1 and provided with an air-chamber 2. Formed in the bottom of said base is an inlet-opening 2, controlled by suitable sliding dampers 2".

Supported upon and extending above the base is an inverted conical hot-air generator 13, the lower end of which extends centrally through the base and opens beneath the same, and surrounding said generator at its contracted end is an annular gas or vapor burner O, suitably mounted upon the base and connected with a supply-pipe 3. As shown, the wall of the generatoris plain. It will be readily understood, however, that it may be formed with either annular or longitudinal corrugations, if desired.

Located above the generator B is an annular top D, formed with a hot-air-distributing chamber 3, which communicates with the interior of the generator through horizontal ra dial passages 4 and a vertical passage 5.

Surrounding the hot-air generator B is a series of vertical air-columns E, which com municate at their upper ends with the airdistributing chamber 3 and at their lower ends with the air-chamber 2 of the base A. These air-columns may be arranged in close juxtaposition in order that the hotairchamber or space 6 intermediate the columns and the air-generator may be practically a closed one; but preferably wide spaces are left between the columns, leaving the burner and generator exterior-1y exposed in order that heat may be radiated into the room from the generator. The inner walls of the columns converge toward the hot-air generator B, and upon their interior the columns are provided with longitudinal ribs 7, the purpose of which will be presently described.

Extending centrally through the top D is a cylindrical discharge-flue 8, which communicates at its lower end with the hot-air chamber 6 and at its upper end with a stovepipe 9, through which the products of combustion pass from the said chamber 6. The said flue also communicates with the u er end of the passage 5.

Projecting from the exterior of a pipe 16, near the upper end thereof and above the radial passages 12, is an annular conical flange 16, which extends partially across the passage 5, and likewise projecting from the interior of the sleeves 10 is a correspondingflange 10. These flanges are so arranged that when the parts are in their normal positions, as shown in Fig. 1, they will rest in contact and close the upper end of the passage 5, thereby directing the hot air through the radial passages 12 into the chamber of the top D. When, however, the sleeves 1O 13 are lowered, the flange 10 will be carried away from the flange 16 and the air ascending through the generator and passage 5 will be permitted to flow into the discharge-flue 8.

The top D is preferably provided with perforations through which the hot air may escape from the air-distributing chamber 3; but, if desired, it may be formed with closed walls, or suitable pipes may beled from the distributing-chamber to convey the hot air to distant points.

Adapted to slide within the passage 5 is a sleeve 10, formed in its sides with openings 12, which normally register with the radial passages 4, and arranged within the lower end of the hot-air generator B is a similar open-ended sleeve 13, which is normally within the generator, but is adapted to be projected below the base to bring its lower end in close proximity to the floor. The two sleeves 10 13 are connected together by means of rods 14, and to the lower sleeve is connected one end of a pivoted lever 15, by means of which the sleeves may be simultaneously raised or lowered.

It is a well-known fact that the foul air in a room by reason of its contained carbonicacid gas falls to the floor of the room, and in order to prevent the flow of this vitiated air through the air-distributing chamber it is only necessary to lift the lever 15 and lower the sleeves 10 and 13 to close the radial passages 4 and bring the lower end of the sleeve 13 close to the floor, when the foul air will pass through the generator B, vertical passage 5, and out through the stovepipe. In order that the greater portion of the vitiated air may be constantly discharged, a pipelG is projected through the generator B, with its lower end normally in close proximity to the floor and its upper end extended into the top of the cylinder 8 above the plane of the radial passages 4:, and this pipe is likewise connected to the end of the lever 15 to be simultaneously operated with the sleeves 10 13.

From the above it will be understood, the parts being in the positions indicated in Fig. 1 and the burner beinglighted, that the flames coming in contact with the exterior of the generator will heat the same as well as the air passing through it to the air-distributing chamber, and the heat from the generator will be radiated into the. room'and to'the aircolumns, causing said columns and the air flowing through them to become heated also, the air being admitted to the passages of the columns through the openings 2 and airchamber 2 of the base. By forming the columns with sides or walls which converge inwardly toward the generator the columns will be sufliciently heated to impart a high degree of heat to the air flowing through the columns; but said converging walls will not obstruct the heat-rays and cause heat to be reflected back to the generator. On the contrary, the heat-rays which strike the converging walls of the columns will merely be slightly deflected and will flow into the room.

In mild weather when very little heat is required the stove may be surrounded by a screen of wire-netting, which serves to prevent the heat being radiated from the walls of the hot-air generator into the room, the heat passing out through the discharge-flue. This screen may be constructed in any suitable manner which will permit it to be readily attached and detached from the stove, and it is not deemed necessary to illustrate it.

Without limiting myself to the exact construction and arrangement of the parts shown and described, since it will be understood that such construction and arrangement may be variously modified and some features of the invention used without others,

In a gas or vapor stove, the combination with a central hollow hot-air generator open at its lower end, of a burner surrounding the generator, a hollow top above and overhanging the generator and communicating therewith, said top being formed with a dischargeflue surrounding the generator, and means for placing the discharge-flue into and out of communication with the interior of the generator, substantially as described.
